Chapter 5: Commands For Configuring Slots And Ports On A Switch - Extreme Networks ExtremeWare XOS Command Reference Manual

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
5 Commands for Configuring Slots and Ports on a
Switch
This chapter describes commands related to:
Enabling, disabling, and configuring individual ports
●
Configuring port speed (Fast Ethernet ports only) and half- or full-duplex mode
●
Creating link aggregation groups on multiple ports
●
Displaying port statistics
●
Configuring switch port mirroring
●
Configuring software-controlled redundant ports and Smart Redundancy
●
Configuring Extreme Discovery Protocol
●
By default, all ports on the switch are enabled. After you configure the ports to your specific needs, you
can select which ports are enabled or disabled.
Fast Ethernet ports can connect to either 10BASE-T or 100BASE-T networks. By default, the ports
autonegotiate (automatically determine) the port speed. You can also configure each port for a particular
speed (either 10 Mbps or 100 Mbps).
Gigabit Ethernet ports with fiber interfaces are statically set, and their speed cannot be modified.
The switch comes configured to use autonegotiation to determine the port speed and duplex setting for
each port. You can select to manually configure the duplex setting and the speed of 10/100 Mbps ports,
and you can manually configure the duplex setting on gigabit Ethernet ports.
All ports on the switch (except gigabit Ethernet ports) can be configured for half-duplex or full-duplex
operation. The ports are configured to autonegotiate the duplex setting, but you can manually configure
the duplex setting for your specific needs.
Flow control is supported only on gigabit Ethernet ports. It is enabled or disabled as part of
autonegotiation. If autonegotiation is set to off, flow control is disabled. When autonegotiation is turned
on, flow control is enabled. (See the ExtremeWare XOS Concepts Guide for more detailed information on
flow control on Extreme Networks devices.)
Link aggregation, or load sharing, with Extreme Network switches allows you to increase bandwidth
and resilience between switches by using a group of ports to carry traffic in parallel between switches.
The sharing algorithm allows the switch to use multiple ports as a single logical port. For example,
VLANs see the link aggregation group (LAG) as a single logical port. The algorithm also guarantees
packet sequencing between clients.
Beginning with ExtremeWare XOS version 11.3, you can use the Link Aggregation Control Protocol
(LACP) to configure and enable dynamic link aggregation. Static link aggregation is still available as
well.
If a port in a link aggregation group fails, traffic is redistributed to the remaining ports in the LAG. If
the failed port becomes active again, traffic is redistributed to include that port.
You can view port status on the switch using the
